Answer 1

The root cause is related migration to Androidx, google play service updated to androidX Thanks to MR03web This problem belongs to react-native-device-info? best option is to upgrade react-native-device-info using

yarn upgrade react-native-device-info@2.1.2
cd android && gradlew clean
react-native run-android

or if you don't want to upgrade you should exclude com.google.android.gms from react-native-device-info like this. Thanks

implementation(project(":react-native-device-info"),  {
  exclude group: "com.google.android.gms"
})
implementation "com.google.android.gms:play-services-gcm:16.0.0"

Answer 2

I had the same problem, just upgrade react-native-device-info and run the following command

npm upgrade react-native-device-info@latest
react-native run-android

Answer 3

Upgrading 'react-native-device-info' to version 2.1.2 fixed the error for me. See github.com/facebook/react-native/issues/25294#issuecomment-503024749

In short: the library used "services-gcm:+" as a dependency, and the latest gcm version caused this problem.

Answer 4

According to @Frank's answer the library used services-gcm:+ as a dependency, and the latest gcm version caused this problem.

And I had used :react-native-admob in my project. So I just change the following lines in android/app/build.gradle

From:

implementation project(':react-native-admob')

TO :

implementation(project(":react-native-admob"),  {
        exclude group: "com.google.android.gms"
})
implementation "com.google.android.gms:play-services-ads:16.0.0"

Answer 5

If you are not using react-native-device-info, but have the same error, its probably another library in your project.

Use this to find the library in question:

cd your-react-native-project/android
./gradlew app:dependencies > deps.txt

Then inspect the deps.txt file for keyword "androidx". Then you can quickly find which native module is using it.

In my case it was react-native-camera, for which solution above was good but not enough so I had to add this to local.properties:

firebaseVersion=17.6.0
googlePlayServicesVersion=16.1.0
googlePlayServicesVisionVersion=16.2.0

EDIT: After these fixes, running ./gradlew app:dependencies > deps.txt and searching for "androidx" returned no results - this is what we are looking for.

After running clean on the project, build worked.

Google play services breaking changes. See Release Notes.

The simple way to resolve this issue is just changing the version of Google play services.

Change all com.google.android.gms:play-services-* dependencies to version 16
